    <p>This might make me look like a pervert, but I searched google for 'sperm' (ofcourse only for .h and .cpp files). The bad news is I can't find any references to it (except on the <a href="http://pubs.opengroup.org/onlinepubs/007904975/functions/stat.html" rel="noreferrer">stat function</a> page itself).</p> <p>The good news is I found <a href="http://code.google.com/p/group1reseau/source/browse/trunk/ftp_server/FTPProcess.cpp?spec=svn11&amp;r=11" rel="noreferrer">this</a> piece of code which defines it's own 'sperm' function:</p> <pre><code>char const * sperm(__mode_t mode) { static char local_buff[16] = {0}; int i = 0; // user permissions if ((mode &amp; S_IRUSR) == S_IRUSR) local_buff[i] = 'r'; else local_buff[i] = '-'; i++; if ((mode &amp; S_IWUSR) == S_IWUSR) local_buff[i] = 'w'; else local_buff[i] = '-'; i++; if ((mode &amp; S_IXUSR) == S_IXUSR) local_buff[i] = 'x'; else local_buff[i] = '-'; i++; // group permissions if ((mode &amp; S_IRGRP) == S_IRGRP) local_buff[i] = 'r'; else local_buff[i] = '-'; i++; if ((mode &amp; S_IWGRP) == S_IWGRP) local_buff[i] = 'w'; else local_buff[i] = '-'; i++; if ((mode &amp; S_IXGRP) == S_IXGRP) local_buff[i] = 'x'; else local_buff[i] = '-'; i++; // other permissions if ((mode &amp; S_IROTH) == S_IROTH) local_buff[i] = 'r'; else local_buff[i] = '-'; i++; if ((mode &amp; S_IWOTH) == S_IWOTH) local_buff[i] = 'w'; else local_buff[i] = '-'; i++; if ((mode &amp; S_IXOTH) == S_IXOTH) local_buff[i] = 'x'; else local_buff[i] = '-'; return local_buff; } </code></pre> <p>usage is simple:</p> <pre><code>#include &lt;sys/types.h&gt; #include &lt;sys/stat.h&gt; #include &lt;iostream&gt; int main(int argc, char ** argv) { std::cout&lt;&lt;sperm(S_IRUSR | S_IXUSR | S_IWGRP | S_IROTH)&lt;&lt;std::endl; std::cout&lt;&lt;sperm(S_IRUSR)&lt;&lt;std::endl; std::cout&lt;&lt;sperm(S_IRUSR | S_IRGRP | S_IWOTH | S_IROTH)&lt;&lt;std::endl; return 0; } </code></pre> <p>output on <a href="http://ideone.com/C9USp" rel="noreferrer">ideone</a>:</p> <pre><code>r-x-w-r-- r-------- r--r--rw- </code></pre>

    1. COI'm also not at work and was able to do some googling, and found this: http://answers.yahoo.com/question/index?qid=20091108232812AA2Vtb4 which references a BeOS function that does about the same thing.

    2. COHi, thanks for finding that, as a quite new C++ person any chance you could tell me how I might integrate that into my code. On another note to add to the humorous banter on this particular question, it's really a great shame that the response from BJ Homer didn't answer the sperm() question as that would have been poetic justice.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
